My invention relates to, rock stackers. The subject matter of this application is disclosed in my application Serial No. 349,417 wherein I show my stacker working with my gold separator for the purpose'of stacking rock's delivered from the screening device ofgs'aid separator. i

The object of the'presentrinvention is to provide a stacker whichcan be swung in the arc of a circle while the conveyor is running.

F1gure 1 represents a side elevatlon of the stacker, partly in section; Fig. 2, a plan viewof Fig. 1, and Fig. 3, an end 6161 8131011.

Although I have shown the preferred embodiment of my invention, I do not thereby limit 11 yself to the form shown, but wish 1t understood that within the scope of what, hereinafter 1s claimed, varlous changes 1n the precise details of construction may ,be made without departing from the. invention.

The stacker comprises the actuating means, the conveyerin'embers, and the swinging and lifting means I The; actuating means comprise plate 78 containing a central depression; a plate? 9 containing a bearing anddisposed on plate 78; a roller bearing race 80 disposed on plate 79; a roller bearing 81 disposed on race 80; a bearing 82 mounted between blocks 83 supported by a truss 84; a hollow shaft 85 journalled in bearing 82; a secondary bevel gear 86 keyed on shaft 85 and disposed on roller bearing 81; a solid shaft 87 journalled ,in hollow shaft 85 and resting on a ball 88; a main bevel gear 89 keyed on hollow shaft'85; a bracket 90 mounted on solid shaft 87; a shaft 91 your nalled in bracket 90; a pulley 92 mounted on 0 end of shaft 91 and a bevel gear 93 Xles jonrnalled in the bearings 95 in the free of said side bars; a cylindrical roller 96a having axlesjournalled in bearings 95 in'the opposite end of said pair of side bars; concave rollers 97 having axles j ournalled in the 0 intermediate bearin s 95; a belt conveyer C mounted on said cylindrical and: concave rol lers; and a pulley 98 mounted on the axle of roller 96 and connected to pulley'92 by a belt B. i 7

The lifting means comprise a 'bail 100 P T ER? hooked to bearings 101 in side bars 94; a

sheave 102 connected to a cross beam-103 supported by posts 104 and 108 a sheave 105 cone nected to cross beam. 103; a winding drum 106 j ournalled in" bearings 106a mounted on post 108. A sheave lll'connected to bail 100 by link 112; and a cable 109 connected to cross beam 103 and run over sheaves 111, 102105 A hopper 110 is v to 'winding drum 1'06. mounted on side bars 94 to guide the rocks into conveyer. i i

The swinging means comprise cables 113'11l, attached to side bars 94 and run through rings 115116 to floor rings 117118, respectively.

To swing the conveyer clockwise, cable 113 is loosened and cable 114 pulled until thedesired radical position is obtained, after which both cables are made fast to their respective floorrings." g

The 'c onveyenis' elevated by operating Winding drum 106 and thereby winding cable 109 thereon.

IAlthoug'h" this slacker maybe used for stacking othefmaterial than rocks, it was primarily designed for use with my; gold separatorl described in said application Ser. No. 349,417. ed on a fragment of a platform 15 which represents the platform 15 shown in said application; The lower ends of the guy cables 119are securedtofplatform 15. g

actuating mechanism is driven by 'apinion'129 meshed withge'ar 89 and mounted on a shaft 121which is journalled in a standard l22.

The material to be stacked falls into the hopper 110 and is car'riedby the conveyor over the roller 96 from which it falls by force of gravity. The concave rollers 97 permit the belt conveyor to sag and form a trough to keep thestones from rolling over the edges.
